Application filed July 25,

This invention relates to shears adapted particularly for the cutting of rubber 1&1 rings and similar 'circular washers and has for an object to arrange the bladesof the shears}.

whereby the jar ring or washer may be easlly and quickly cut by a single operation in unbroken form from a flat sheet of maerial.

A further object is to provide an article-of this character of simple and practical con-' struction, efiicient in operation inexpensive to manufacture, and otherwise well adapted for the purposes for which the same is in tended. I

Other objects and advantages reside in the 1 special construction andcombination of the various elements of this invention, reference bein had to the accompanying drawings b forming apart hereof, wherein j V Figure 1 is a top plan View of a pair of 2O shears constructed in accordancewith my invention. V I

Figure 2 is a side elevational View thereof,

Figure 3 is a vertical sectional view taken along a'line 3-3 of Figure 2,

Figure l; is a plan view of a fragment of material in sheet form, andfolded upon itself in position for cutting a circular washer therefrom, and, s j p Figure 5 is a plan View of the washer after being cut from suchmaterial.

Referring now-to the drawing wherein for the purpose of illustration I have disclosed a preferred embodiment of my nventlon I provide a pair of shears includlng handle sections 5 secured at one end by'a' Sprmgmemher 6 of atype adapted to normallymaintai'n the handles in a spread position and having blades 7 formed at the opposite ends thereof;v

Each of the handles 5 are provided with a pair of blades arrangedin opposedrelation andas indicated by Figure 2 of the drawing with the cutting edges 8 thereof arranged in alined position for-simultaneous cutting action. i

1927. Serial No. 203384.;

The ends of the blades are'curved upward V ly in semi-circular formation, with the blades of-each handle made 1n an evenly spaced parallel" position with respect to, each other.

I Thus the upper blades 7 which are uppermost atthe connectionthereof with the handles are disposed under the lower blades- 9 at theter mination of the ends thereof. ,With the blades arranged in the manner as described above the same areadap'ted to cut a. continuously formedcircularwasher as indicated at 10 from a sheet-of material 11 such as shown in Figure 4, it first being necessary to fold the material upon itself and to cut the washer from the folded edge as shown by the dotted llnes indicated at 12.

rubber materialand has been found that old inner tubes are especially adapted 'for The device is admirably adaptedfor cutting rubber ar rings andthe like from'sheet stood, however that the'tool may be used for cutting washers or rings from any material I such as papencardboard; sheet cork or the like; .and also from relatively soft metal.

It is obvious that the" invention is suscepti-' ble to various changes in the shape, size and form thereoftwithout departing from the spirit or scope of the appended claim, and I the deacc'ordingly claim all such forms of vice to which Iam entitled.

I claim ';In' atool of the class described, a plurality of cutting blades arranged in pairs in opposed. .relation', the outer. endof each palr of blades being curved i-na semi-circular formation an retained in spaced parallel relation with each other; said blades co-acting. with-each other whereby to cut a c rcular washer from a sheet of material when arranged in folded position atone cutting operation. r e I In testimony whereof I afiix my signature;
